a. both the frequency and the wavelength are the same as in air
b. the frequency is the same, but the wavelength is greater than in air.
c. the frequency is the same, but the wavelength is smaller than in air.
d. the wavelength is the same, but the frequency is greater than in air.
e. the wavelength is the same, but the frequency is smaller than in air.
